The particular illustrated machine comprises a-conveyor '10, formed of a pair of endless chains arranged side by side and preferably extending throughout the length of'the'machine and'which grips'the upper portions of a book which is 'fed to it at one end and retains this same gripupon the book 1929. Serial No. 369,862.

until it is discharged at the opposite end. This leaves the lower, or unsupported, end of the book free to be grasped by other conveyors represented at 11, 12'and'l3 arranged in series lengthwise of the machine directly elow the conveyor 10 and which assists in performing various operations upon the book.

In the machine shown the conveyor 11 holds the lower edge of the book firm while it is being trimmedby trimming mechanism represented at 14, (Fig. 1) and also while a transverse notch or groove is produced therein by means of a rotary saw device as shownand described in my application above referred to.

The conveyor 12 operates to fan the lower cut portion, or'back-edge, of the book to one side so as to expose overlapping edges of the sheets to gluing mechanism represented at lG-(Fig. l).

The conveyor 13 is provided for holding the lower portion of the book again in a fiat position while a super is applied thereto by the mechanism 17 in accordance with my present invention ano as hereinafter fully described; the conveyor 13 also holding the lower portion ofthe book while a cover is applied to the back of the book and firmly pressed of mechanism represented at 18 following the operation of which the book passes out through the chute at the end of the machine to cross-feeding mechanism 19.

The two endless elements comprising the long conveyor 10 are carried by a suitable frame supported on the standards 20, 21, 22 and 28, and engage, at opposite ends of the machine, with'horizontally disposed sprockets keyed to vertical shafts. These shafts at the tail end of the-machine are represented at 24 and 25 (Fig. 2) and the sprocket referred to on shaft 24, at 26 (Fig. 2).

The shafts 24 and 24 are provided at their upper ends with worm wheels, the one on thereagainst by means shaft 24 being represented at 27 (Fig. 3) which mesh, respectively, with worms, the one meshing with the worm wheel 27 being shown at 28, on shafts 29 and 30, which are carried in suitable hearings on the main frame and which extend substantially the full length of the machine.

The shafts 29 and 30 are operatively connected together by means of gears 31 and 32 (Fig. 8) of the same "We provided on these shafts and meshing .1 an idler gear 33, whereby the shafts 29 and 30 are caused to rotate in the same direction and at the same rotative speed.

The shafts 29 and 230 are driven by a motor represented at 34, 8) through a belt connection 35 between pulleys and 37 on the motor shaft and the shaft 30, respectively.

The conveyor likewise formed of a pair of endless chain elements, is located directly beneath the conveyor 10', both of the endless elements of c: e; or 13 operatively engaging at each end hith a sprocket. The sprockets for the conveyor 13, at the tail end of the machine are represented at 38 and 39 these sprockets the vertical shafts 24 and the conveyor 13 thus operating at the same speed as the conveyor 10.

The conveyors 11 and 12 are also driven from the shafts 29 and 30 at the same speed as the conveyor 10 and the chain element of each conveyor 10, 1]., 12 and 13, at one side of the longitudinal axis of the machine, to-

gether with their operating" shaft 29, are adjustable crosswise of the machine for adapting them to operate on books of different thicknesses.

The endless chains of the various conveyors are formed of links pivotally connected together by means of pins. The links of the conveyor 10 are represented at 40 and 41 (Fig. and their connecting pins at 42. The links for the conveyor 13 are represented at 43 and 44 and their pins at 45. The conveyors 10 and 13 also comprise facing links 46 and 47, respective y, likewise mounted upon the pins 42 and respectively, and at which the conveyors grip the books for feed ing them through the machine. The pins 42 and have rollers 48 and 49, respectively, mounted thereon which are adapted to roll upon back plates 50 and 51, respectively, carried by frame members and 53. Thus the pressure of the book, represented at 54, shown in Fig. 9, is taken by the facing links referred to and transmitted through the pins and rollers thereon to the plates 50 and 51. Each link 46 is provided with a roller F 0.) which runs upon a horizontal member 56 (Fig. the member 56 being firmly held by the frame members and 53. Each link 47 of the lower conveyor 13 is provided with a roller 57 which rolls upon. a lower,

horizontal, member 58; and with an upper roller 59 adapted to bear upwardly against the member 56 in case upward pressure is exerted against this lower conveyor.

The endless chains of the other lower conveyors 11 and 12 are preferably constructed as described of the conveyor 13 and are associated with channeled members serving as a backing and guiding means for the chains, as described of the conveyor 13.

In the machine shown, books are fed to the bookbinding machine by means of a conveyor belt 60 (Fig. 1) which passes over a sprocket 61 driven by means of gears, (not shown), from a shaft- 62 which has a worm wheel 63 driven by a worm on the shaft 29. The belt 60 has a series of lugs 64 which feed the book to'the conveyor chains 10 in definit-e timed relation thereto so that the books are always in step with the several mechanisms of the bookbinding machine, particuarly the super feeding mechanism 17.

It will be understood that the book, on entering the machine,'becomes engaged near its upper part by the endless chains of the upper conveyor 10 which operate to retain a firm grip upon the book throughout its travel through the machine.

The gluing mechanism 16 comprises a glue-pot 65 (Fig. 1) containing roller means preferably formed of two rollers 66 arranged in line lengthwise of the machine and journalled to extend at their lower portions into the glue, hese rollers being so positioned that in the lengthwise movement of the book by the conveyor mechanism referred to the lower edge of the book is engaged by the peripheries of these rollers to apply glue thereto, the facing links of the conveyor 12 being preferably laterally deflected in the same direction to cause the sheets of the book at its lower edge portion to become fanned before reaching the gluing mechanism and while mo 'ing in engagement with the peripheries of the gluing rollers, as more specifically described in my said above entitled application.

Referring now to the super-feeding mechanism 17 (Figs. 1, 4, 5, 6 and 7 and which operates on the books after the gluing op eration referred to, it comprises a frame 67 (Fig. 4) provided with a bracket 68 on which is ournalled a reel 69 having spirally wound thereon a band of loosely woven material 7O commonly called super which is to be placed upon the glued back of the book and between it and the cover applied to the book by the mechanism represented at 18, the super material 70 passing between rollers 71 and thence between feed rollers 7 2 and 73.

The feed roller 73 (Fig. 7) comprises an outer sleeve which is mounted upon a core 7 4, the latter being journalled upon a sleeve 75 which is keyed on a shaft 76. The core es atwi be explai e he slee e e a h balls h n t is' eie is rotated in counterclockwise direction in F 7, thereby advancing the roller 7 3 and the super fabric 170. the sleeve 75 r a m in eeh se ehreet en ih hell 7 are rolled back out'of pressurercontactwith the sleeve 75 sothat the roller '73 is adh ehly sh ne e uhte eleekw m ement of the sleeve 75. p

Theshaft carries a gear 92 which meshes with gears 93 and 94 by which the shafts 95 and 9,6 are driven. The shafts 95 and 9 6 carry parallel cranks 97 and 98 having pins 99 which are journaled in a side of the hOllQW box so the latter is given maining horizontal;

The shaft 96 carries a cam 1 00 in which operates a cam iiolloyyer The cam follower 101 carried lever arm 102 which is pivotally mounted at 103, the mov able end of the letter 102 being connected by means of pin 10% link 105, the opposite end .of link being pi Qtally connected to a lever 106 which is keyed to circular i n t e r p al ay the shaft 76.

It will be nnderst o od from the foregoing that on each revolution of the shaft 96 the am acting through the lever 102, the link 105, the lever 106 and the ratchet mechanism shown in 7, advances the super fabric 70 from the position shown in Fig. 7 in full lines, to the dotted line position 70. At this time the hollow box 82 is in a position which will permit the super 70 to be fed beneath the 80. The upper portion of this hollow box carries a hardened metal top 107 haying a shearing edge 108 which, 0;; its next upward movement passes the shearing edge of the knife 80 and serves to shear ofi the portion 70 of the super. strip thus severed fa s upon th met hQ-P 97 an i h n controlled by snction pparatus which will now be described.

It is, of

course, essential that the timing of the super-feeding mechanism be such that it operates in timed relation to the feed of the main conveyor 10. so that the super will fall at the proper point on the book.

The book, with the super applied thereto as stated, then passes to the cover-applying mechanism 18 the construction of which is the same as that set forth in my said above entitled application and which operates to exert upward force against the portion of the cover which extends beneath the edge of the book to which the super was previously applied and also to squeeze the lower edge of the book to firmly secure together the sheets of the books, the super and the cover. While I have shown and described a par-- ticular embodiment of my invention, I do not wish to be understood as intending to limit it thereto, as the same may be variously modified and altered without departing from the spirit of my invention.
